Post Malone and Swae Lee have reached a major milestone for the first single to ever reach double diamond.

They reached this milestone from their song together in 2018 Spider-Man: Into the Spider-Verse single ‘Sunflower’ which reached 20 million+ sales.

RIAA Chairman and CEO Mitch Glazier made a statement about the milestone and said, “Post Malone and Swae Lee have officially raised the bar on what creative partnerships and infectious collaborations have the power to accomplish.”

Post also has 7 diamond singles which is the most in music history.
